Background technology
Take in the substrate box of employed substrates (glass substrate) such as liquid crystal indicator and have various substrates (for example with reference to patent documentation 1) being used for multistage.This base plan is seen as rectangular lamellar, and its size is 500mm * 600mm, follows the development of technology in recent years, and the substrate of 2000mm * 1800mm is also arranged.And, disclose various technology (for example with reference to patent documentation 2) as being used for that described substrate is moved into the technology of taking out of substrate box.
As shown in figure 11, at the inboard face of existing substrate box 1C ', the support unit 51 that is used for supporting substrates 1G both ends is outstanding with predetermined distance on short transverse, is formed for supporting the frame 1R of described substrate 1G with crossing over multistage.Each the substrate 1G that is incorporated in substrate box 1C ' has only support unit 51 supportings of their both ends by correspondence.In this case, deflection appears in the central portion of each substrate 1G, therefore move into have when taking out of with under substrate 1G disturb may.In addition, take out of each substrate 1G, must make the substrate of substrate ejector 1B (with reference to Fig. 5) draw arm 52 and also can enter in order to move into.For preventing these unfavorable conditions, must increase the height (frame, spacing 1H) of each frame 1R.Its result reduces the sheet number of taking in of the substrate 1G of a substrate box 1C '.
For preventing above-mentioned unfavorable condition, known have as shown in figure 12, along substrate box 1C " left and right directions draw close plating silk 53 and form the technology of each frame 1R thus.At this substrate box 1C " situation under, only carry out the band roller framework 54 of lifting and promote substrate 1G, and move in this state and take out of this substrate 1G by connecting its bottom surface sections.But, when taking out of substrate 1G, must begin to take out of successively the substrate 1G of epimere from the substrate 1G on the frame 1R that is accommodated in hypomere.In addition, when taking in substrate 1G, need begin to be received into successively in the frame 1R of hypomere from the frame 1R of epimere.Therefore, take out of the substrate 1G on the frame 1R that is accommodated in any section or substrate 1G to be received on the frame 1R of any section be difficult.
In addition, the semiconductor element that forms on such substrate is being under the situation of an operation group with continuous different a plurality of operations, consists of multilayer and is formed on the substrate via same or approximate a plurality of operations.
For example, in substrate W shown in Figure 26, after utilizing cleaning device A that substrate W surface is cleaned, utilize CVD device B to form oxide-film 151 on its surface.Then, utilize electro-optical device (Off オ ト device) C on described oxide-film 151, to apply emulsion 152, and expose and develop according to exposing patterns.Then, utilize Etaching device D that the part beyond the exposing patterns is melted, and then remove emulsion 152.Thus, form the ground floor semiconductor element on the surface of substrate W.Also some substrate W strides multilayer and forms semiconductor element on its surface, and in addition, the forming process of each layer also has and different situation shown in Figure 26.
Therefore, as shown in figure 27, in a plurality of operation groups of each layer that forms semiconductor element, to handle a plurality of processing unit A～D of same or approximate operation with state configuration arranged side by side, perhaps will dispose relatively with the device of state configuration arranged side by side, to be configured in a place to the processing unit group concentrated area that is called as " segmentation (ベ イ) " that each layer carries out same or approximate processing, a plurality of " segmentations " corresponding with the process number of each layer will be arranged on different place (for example with reference to patent documentation 3).
And the carrying of substrate is carried out under the state that multi-piece substrate is accommodated in the case, and in whole operations, same processing (batch processing) is carried out in the multi-piece substrate concentrated area that is accommodated in the case.The special-purpose carrier 153 that the mobile utilization of the substrate in batch between each segmentation (being meant the multi-piece substrate that is accommodated in the case) connects between each segmentation carries out.For the ground of multilayer on substrate forms semiconductor element, substrate in batch is that unit will be back and forth between each segmentation of the operation of front and back with every layer.In Figure 27, label 154 is the windrow devices that are used for interim placing box.
Like this, above-mentioned " segmented mode ", be carried out to batch processing for multi-piece substrate is concentrated in each operation, begin to become and quite grow (with reference to Figure 22) to the processing of the whole operations of end and the time that comprises whole stand-by period (the making time T 12 of goods) that becomes in the needed manufacturing line of finished product (goods) from substrate being dropped into manufacturing line.Its result, be stranded in the manufacturing line owing in manufacturing line, there are many semi-finished product (make midway unfinished work) to be in inventory status, therefore as mainly elongated to the delivery cycle (delivery date) that referable is finished during the product from counting delivery after ordering.Therefore, be unsuitable for the manufacturing of short goods at delivery date.In addition, owing to goods cause and can not calculate as goods in system time T 12 length, the quantity of the unfinished work that is detained as the stock in manufacturing line (at product inventory) is many, so consider turnover rate (rate of recovery) variation that makes capital invested from the operation aspect.And in recent years, because substrate becomes big and becomes expensive with this, therefore above-mentioned problem becomes more obvious.In addition, " goods are in the system time " reaches " at product inventory " and is known as " TAT (Turn Around Time) ", " WIP (Work-in-process) " respectively, and the former abbreviation " TAT " uses in the following description.

The processing unit of the past operation is the processing unit carrying substrate of operation backward, owing to be disposed at the temporary transient substrate of placing on the interim mounting table of first between each processing unit, and utilize the substrate delivery/reception device that substrate is carried operation backward successively via the described first interim mounting table, even so productive temp time (needed time of the processing of processed continuously each substrate in this processing unit of each processing unit, or processed continuously substrate relatively this processing unit making time at interval or at interval from the efflux time of this processing unit) how much have a deviation, each substrate delivery/reception device can be not and the action of the substrate delivery/reception device of the operation of front and back (not linking) synchronously yet, and carry out the handing-over (carrying) of substrate independently.
Though directly handing-over is handled midway and (is meant the processing that finishes the specific operation in whole operations between each substrate delivery/reception device of front and back, the state of the processing of remaining residue operation) substrate, there is the baroque problem that makes substrate damage or make the substrate delivery/reception device, but owing to the board carrying in will handling via the first interim mounting table arrives the back operation, so above-mentioned each problem is eliminated.
Owing to being flows through substrate along each the sheet ground of processing unit group by the process sequence configuration to carry out the mode that multiple operation is handled, so goods shortened in the system time.Therefore, because with after same processing is carried out in the multi-piece substrate concentrated area, " segmented mode " that ensuing operation is carried out in same concentrated area compared, described goods obviously shortened in the system time, and the quantity of the substrate that becomes in manufacturing line at goods (unfinished work) and be detained also significantly reduces, therefore, the delivery cycle (delivery date) shortens, and can tackle short delivery delivery date or immediate delivery phase.Its result, at the method for making semiconductor that above-mentioned board carrying method has feature, from the operation aspect, the recovery of investment (turnover) becomes soon, thereby has improved turnover of capital (rate of recovery).

The processing substrate midway that carries out attached processing after utilizing the substrate delivery/reception device to be placed on the second interim mounting table temporarily, given substrate branch road carrier and be moved to attached processing unit by handing-over via the branch road path, after processing, utilize described substrate branch road carrier to be transported to be disposed at and to carry out the locational second interim mounting table that subsequent processing handles and placed temporarily.Then, attached substrate of handling and common substrate similarly are handled upside down by untreated each process sequence via regular carrying road.Because the productive temp time of each operation is set to constant, so when extracting and when finishing attached processing and turning back to regular carrying road by above-mentioned extraction, by the operation with extraction is benchmark, till the processing that finishes regulation sheet number, change the productive temp time (when extracting in the operation before and after it, the productive temp time of back operation is shortened, returning when original, productive temp time of preceding operation is shortened), make after this to become the original productive temp time and handle swimmingly.
Wherein, in failure and other reasons owing to the particular procedure device, and have under the situation of other substrate being disposed on locational first or second the arbitrary interim mounting table that extracts, behind the substrate that has extracted attached processing usefulness, by other substrate operation carrying (flows direction) backward that will be through with the substrate same treatment of described extraction, under constant state of the productive temp time of keeping back operation, carry out the processing of substrate.
In addition, the present invention is a prerequisite with described invention, it is characterized in that, the carrying that temporarily is positioned over the substrate on the described second interim mounting table utilizes the carrying of the second interim mounting table self to carry out.Often the substrate of the second interim mounting table to move into mouthful and take out of the identical design of mouth more, yet, owing to the second interim mounting table is configured between regular carrying road and the branch road carrying road, so by the carrying second interim mounting table self, and will not move into mouthful (taking out of mouth) two places are not set.
In addition, the present invention is a prerequisite with described invention, it is characterized in that, by the processing unit group that a plurality of processing unit constitute, is cut apart by two and configuration relatively along regular carrying road, is constituted branch road carrying road between two each processing unit group of cutting apart.Because the processing unit group both sides correspondence of branch road carrying Lu Yuqi both sides, so with regular carrying road is that the situation of straight line is compared, its length becomes half, makes to utilize substrate branch road carrier needed time of carrying substrate between the attached processing unit and the second interim mounting table to shorten.
In addition, the invention provides a kind of device, be on substrate, to form in the semiconductor-fabricating device of semiconductor element via multiple working procedure successively, carry the device of described substrate along the processing unit group that constitutes by a plurality of processing unit by the process sequence configuration for the processing of carrying out each operation, it is characterized in that, have: conveyer, it is used for each sheet ground carrying substrate along the orientation configuration of each processing unit; And the substrate delivery/reception device, it is configured between described conveyer and each processing unit, is used for carrying out between the two the handing-over of substrate, wherein, will be utilized the processing unit carrying of operation backward of described conveyer by the substrate that described each processing unit is handled.
Owing to being flows each ground of substrate along the processing unit group by process configurations to carry out the mode that multiple operation is handled, so goods were shortened in the system time.Therefore, with after same processing is carried out in the multi-piece substrate concentrated area, similarly concentrate " segmented mode " that carry out next processing to compare, described goods obviously shortened in the system time (TAT), and, the quantity of the substrate that becomes in manufacturing line at goods (unfinished work) and be detained is also significantly reduced, therefore shortened the delivery cycle (delivery date), thereby can tackle short delivery delivery date or immediate delivery phase.Its result, the method for making semiconductor that on above-mentioned board carrying method, has feature, from the operation aspect, the recovery of investment (turnover) accelerates, thereby has improved turnover of capital (rate of recovery).
In addition, the present invention is a prerequisite with described invention, it is characterized in that, described substrate is carried under the state that is accommodated on the pallet.Though when substrate is carried under directly by the state of mounting on conveyer, have substrate with contact-making surface conveyer contaminated or damage may, in the present invention because substrate is housed inside on the pallet, so can not produce such worry.
In addition, the present invention is a prerequisite with described invention, it is characterized in that, disposes the substrate storage device that is used for temporarily taking care of the substrate that processing that described processing unit carries out finishes in the positive downstream of the processing unit of conveyer.Even because the fault of processing unit of back operation or mainteinance repair etc. can not be with board carrying operations backward, also can temporarily take care of on the substrate storage device, thereby the substrate that the processing of operation finishes before making can be with constant state (for example remaining the state that is contained in the processing unit) delay always by the substrate that will handle midway (processing that refers to the operation of this upstream side finishes).
In addition, the present invention is a prerequisite with described invention, it is characterized in that, described conveyer is an annular conveyer, be used for each the processing unit assembly that forms semiconductor element on the substrate place annular conveyer around.In the present invention, conveyer is an annular conveyer, and each processing unit assembly places around it.Therefore, even, also can reduce the whole area that is provided with forming under the situation of semiconductor element and a plurality of processing unit of necessary configuration in order to stride multilayer on the substrate.
In addition, the present invention is a prerequisite with described invention, it is characterized in that, for the substrate of handling is midway carried out attached processing, manages the branch road Handling device that can carry described substrate between the device throughout and dispose.Therefore,, or break down and substitute when handling with other processing unit at arbitrary processing unit in the extraction inspection of handling substrate midway, can be with board carrying to described other processing unit, thus improved the treatment effeciency of substrate.
The invention is characterized in, by constituting: substrate box as the lower part, its inside at box main body is formed with a plurality of of multistage supporting substrates, and the particular side of described box main body becomes moving into of substrate and takes out of opening, and described is made of a plurality of Zhi Chengcai that connect box main body with predetermined distance; And substrate elevating unit, it makes substrate elevating plate with substrate lifting device pass in and out respectively in the described substrate box from the side of described substrate box, and under described substrate elevating plate enters into state in the substrate box, with directly over substrate from described Zhi Chengcai, lift a little, wherein, described substrate box and described substrate elevating unit relatively carry out lifting.Therefore, can take out of the substrate on any frame that is accommodated in substrate box with not damaging, and substrate can be moved in any frame of substrate box.

As Figure 15 and shown in Figure 16, the substrate delivery/reception device Ea that is provided with accordingly with the first cleaning device A11 has following function, take out of (drawing) and be accommodated in the substrate W that carries with in the substrate box 104, it is moved into the first cleaning device A11, and, the substrate W of the clean that is through with is taken out of from the first cleaning device A11, it is accommodated in the main substrate case of being located between the first cleaning device A11 and the CVD device B1 101.And, the substrate delivery/reception device Eb that disposes accordingly with CVD device B1 has following function, take out of the substrate W that is accommodated in the described main substrate case 101, it is moved into CVD device B, and, the substrate W that is through with in the processing of described CVD device B1 is taken out of from this CVD device B1, and it is received in the main substrate case of being located between the CVD device B1 and the second cleaning device A12 101.Therefore, each domain of walk Ra, Rb of substrate delivery/reception device Ea and substrate delivery/reception device Eb repeat in the part of main substrate case 101.
Like this, the substrate W that is accommodated in the main substrate case 101 is taken out of by substrate delivery/reception device Ea, Eb arbitrarily, and is moved in each processing unit A～D.In addition, the substrate W of the processing undertaken by each processing unit A～D of being through with is taken out of by substrate delivery/reception device Ea, Eb arbitrarily, and is received in the main substrate case 101 of back operation side.Below, by carrying out above-mentioned operation repeatedly, the processing that enforcement is undertaken by each processing unit A～D to substrate W.Therefore, be incorporated in the sheet number of the substrate W in the described main substrate case 101, (in other words, the situation that each processing unit A～D is successfully worked) is a slice under normal conditions.
Main substrate case 101 is described.As shown in figure 17, the main substrate case 101 of present embodiment is a cuboid frame shape, takes out of substrate W in order to move into, and its face relative with substrate delivery/reception device Ea, Eb is by opening.And (device orientation Q) is equipped with many wire 112 with the state of giving tension force along its Width.These wires 112 are installed with predetermined distance in short transverse, at each section substrate depositing rack 113 that to be formed with described wire 112 be frame plate.Thus, can in a main substrate case 101, take in multi-piece substrate W multistage.And this main substrate case 101 is first-in first-out mode (First-in First-out).That is, by making lifting arm 114 turnover main substrate casees 101 from its side, the substrate W that is accommodated on the substrate depositing rack 113 of any section can be broken away from a little from each wire 112.Therefore, can carry out arbitrarily moving into of substrate W takes out of.Its result, (fault of each processing unit A～D etc.) and in described main substrate case 101, taken in substrate W even for a certain reason more than or equal to two, also can take out the substrate W that FEFO is handled earlier, thereby can prevent because processing substrate W midway is placed the reduction of the quality of item that produces etc. for a long time.Like this, main substrate case 101 of the present invention not only has the function of the substrate W that handing-over temporarily is set temporarily, also has following function, manage throughout under the situation that device A～D breaks down, make the substrate W that is stranded in the operation of this upstream side break away from the flow process of manufacturing line, temporarily take in, promptly have the pooling feature of manufacturing line.
Relative therewith, check that be the example of formula according to the order of sequence with substrate box 102 and carrying with substrate box 104.As shown in figure 14, identical with above-mentioned main substrate case 101, be provided with substrate depositing rack 113 with utilizing each wire 112 multistage, and, under each substrate box 102,104, be provided with liftable band roller frame 115.Under moving into the situation that is accommodated in the substrate W in these substrate boxes 102,104, described band roller frame 115 is risen, and make the substrate W on the substrate depositing rack 113 that is accommodated in hypomere break away from wire 112.Under this state, the vacuum absorption device 107 of utilization formation substrate delivery/reception device Ea, Eb or supporting arm 109 are moved into and are taken out of described substrate W.In the situation of the substrate box 102,104 of this structure, the simple advantage that becomes of the structure with device (band roller frame 115) that substrate W is risen.In addition, this is checked with substrate box 102 and also can in this case, can carry out the arbitrary access of the inspection operation of substrate W for the substrate box of the mode (first-in first-out) identical with main substrate case 101.
Secondly, the branch road carrying road to substrate transfer apparatus S describes.In semiconductor-fabricating device U,, have from the operation of regulation and extract the situation of handling substrate W midway for carrying out the extraction inspection of substrate W.The substrate W that described branch road carrying road is used for extracting is transported to testing fixture Ma, the Mb place of each group.For example, in the ground floor forming process P1 of present embodiment, as shown in figure 18, the inspection that is respectively equipped with the substrate W that is used to take in extraction in the part of the interim mounting table row of the substrate L2 corresponding with electro-optical device C1 and Etaching device D1 of ground floor forming process P1 is with substrate box 102.This means that in the ground floor forming process P1 of present embodiment, the substrate W of the processing that the electro-optical device C1 that is through with is carried out or the substrate W of the processing that the Etaching device D1 that is through with carries out extract inspection.
As shown in figure 14, constituting on the branch road carrying row L3 on branch road carrying road, Q is equipped with pair of guide rails 116 along the device orientation, disposes branch road carrier 103 on this guide rail 116.This branch road carrier 103 can be walked freely by described guide rail 116 guiding.In addition, be provided with case connection device 117 on this branch road carrier 103, it has the inspection substrate box 102 that the substrate W of extraction is taken in acceptance, and gives the function of testing fixture Ma, Mb with its handing-over, and has the function of carrying out its adverse effect.
Each arrow of Figure 18 is represented the flow direction (portable cord) handled for the substrate W that extracts.As shown in figure 18, extract the substrate W of inspection by substrate delivery/reception device Ea, Eb are received into inspection with in the substrate box 102 arbitrarily.Take in the inspection of this substrate W and given branch road carrier 103 by handing-over with substrate box 102 former states ground.Then, utilize described branch road carrier 103 to be transported to the approximated position of the testing fixture Ma of the interim mounting table row of substrate L2, and by mounting on the described approximated position part of the interim mounting table row of substrate L2.This substrate W moves into testing fixture Ma by the substrate delivery/reception device Ea that disposes accordingly with testing fixture Ma.The substrate W of the inspection that the described testing fixture Ma that is through with carries out is received to and checks with in the substrate box 102, and subsequent processing position that utilizes branch road carrier 103 to be transported to once more to extract operation and mounting are to the interim mounting table row of substrate L2.
Secondly, the effect to substrate transfer apparatus S describes.Only the handing-over effect from the first cleaning device A11 to the substrate W CVD device B1 is described at this.As shown in figure 19, the substrate delivery/reception device Ea of corresponding first cleaning device A11 configuration is moved, with itself and carrying substrate box 104 relative configurations.Be accommodated in described carrying and taken out of also mounting to the base 106a of substrate delivery/reception device Ea from carrying with substrate box 104 by the vacuum absorption device of being located on the substrate delivery/reception device Ea 107 with the substrate W in the substrate box 104.Then, make described base 106a Rotate 180 ° in horizontal plane.Under this state, make substrate delivery/reception device Ea downstream side (back operation side) move, with the first cleaning device A11 move into opening 118 relative configurations.Substrate W is moved in this device A11 via the opening 118 of moving into of the first cleaning device A11 by being located at the effect of the vacuum absorption device 107 on the substrate delivery/reception device Ea, carries out clean, and takes out of opening 119 from this and take out of.
As shown in figure 20, when carrying out the clean of substrate W, substrate delivery/reception device Ea is along device orientation Q operation side shifting backward, with the first cleaning device A11 take out of opening 118 relative configurations.Utilize and above-mentioned effect much at one, the substrate W that takes out of from the first cleaning device A11 once more by handing-over to substrate delivery/reception device Ea, and former state be moved to the position relative with main substrate case 101.And described substrate W is incorporated in the main substrate case 101.Described substrate delivery/reception device Ea is moved to and carries with the relative position of substrate box 104, and repeats above-mentioned effect.
Then, as shown in figure 21, when being accommodated in substrate W in the main substrate case 101 and substrate delivery/reception device Ea is retreated, the substrate delivery/reception device Eb of corresponding CVD device B1 configuration is moved, with described main substrate case 101 relative configurations.Utilization is located at the effect of the supporting arm 109 on the substrate delivery/reception device Eb and is taken out of substrate W from main substrate case 101.This substrate W is moved operation side backward in mounting under the state on the described substrate delivery/reception device Eb, so in horizontal plane by with predetermined angular rotation, and with CVD device B1 move into opening 121 relative configurations.Then, moved in the CVD device B1.
The substrate W of the processing among the described CVD device B1 of being through with is received in the main substrate case 101 of subsequent processing by substrate delivery/reception device Eb.Afterwards, the second cleaning device A12, electro-optical device C1, Etaching device D1 carry out effect much at one.And, as shown in figure 15, in first group of processing unit A～D, the substrate W that takes out of from the CVD device B3 that is disposed at downstream part utilizes substrate delivery/reception device Eb to be received into carrying with in the substrate box 104, and, utilize described track carrier 105 to be transported to second group of processing unit A～D place utilizing the temporary transient mounting of branch road carrier behind the approximated position of the track carrier 105 of the interim mounting table row of substrate L2.And then, in second group of processing unit A～D, carry out effect much at one.
Next, the processing time of the substrate W on the above-mentioned regular carrying road of explanation of comparing with existing segmented mode.Figure 22 is the mode time figure of the flow direction of the substrate W of expression will handle midway substrate W and utilize monolithic processing and batch processing normally to handle the time.In addition, in Figure 22～Figure 24, owing to be the mode time figure that is used to understand the normal flow direction of substrate W, so less than not corresponding with the treatment process of described embodiment and reduced its operation quantity.Below, when expression one plate base W, additional " 1 "～" n " label.In addition, the processing time of each processing unit (productive temp time) is set at roughly the same.
In monolithic of the present invention is handled, (W1～Wn) is setting after the productive temp time (T1) drops into the processing unit of operation (I) and handle, and dropped into the processing unit of operation (II) and handles via main substrate case 101 (the first interim mounting table) for each substrate.And then the substrate W that takes out from the processing unit of operation (II) drops into the processing unit of operations (III) via other main substrate case 101 and handles.Like this, not for check to handle that midway substrate W extracts or the situation of the normal process that specific processing unit does not break down under, each substrate (W1～Wn) only temporarily be positioned in each main substrate case 101, and be not incorporated in the described main substrate case 101, and flow to lower procedure successively, in each operation, handle with the roughly the same setting productive temp time (T1).
Describe particularly above.Under situation of the present invention, as shown in figure 22, when the first plate base W is dropped into operation (I), utilize the processing unit of this operation (I) that substrate W1 is carried out predetermined process.When this processing finished, this substrate W1 dropped into the processing unit of operation (II) via main substrate case 101 (the first interim mounting table).Follow this, the second plate base W is dropped into the processing unit of operation (I).Like this, in the present invention, (monolithic processing) handled by input each operation (I), (II), (III) in each sheet ground of substrate W1～W3.Relative therewith, in existing segmented mode, handle owing to be that unit is concentrated with each operation, so the processing time of each operation is elongated with multi-piece substrate W.But in situation of the present invention, the TAT of each substrate W1～W3 (T2) compares with the TAT (T12) of the situation of segmented mode, and compole is short at that time.In addition, the productive temp time T 1 of each substrate W1～W3 of the present invention is also short than the productive temp time T 11 of segmented mode.
In addition, graphical presentation shown in Figure 23 monolithic of the present invention is relatively handled and the relation of the processing sheet number of the substrate W of time of batch processing.In the figure, the situation that solid line 122 expressions monolithic of the present invention is handled, the situation of the existing segmented mode of double dot dash line 123 expressions.This figure is from substrate W being dropped into behind the manufacturing line to the total processing time that is removed needed every plate base W1 as the product of finishing, and it is identical being assumed to be in monolithic processing and batch processing.In existing segmented mode, because for example 20 plate base W focus on, so, then can not obtain as the substrate W that finishes product if through this TAT (T12).But, in situation of the present invention, owing to be the mode that each sheet ground is handled, so if the TAT (T12) of process a slice then produces a plate base W.
Above-mentioned result is, the quantity that becomes the substrate W (at product inventory) that is detained at goods (unfinished work) in manufacturing line also reduces, as long as few running fund can reclaim at short notice with respect to investment, therefore, the managerial advantage that has the good grade of turnover of capital.In addition, owing to, the keeping space of the substrate W in the manufacturing line is reduced, therefore has the low advantage of construction cost of clean room by reducing at goods in the storehouse.Particularly in nearly a period of time, because increasing the unit price of every plate base W1, the size of substrate W also increases, thus make the shortening of above-mentioned TAT or in the product inventory minimizing, thus big benefit produced.In addition, the delivery cycle (delivery date) shortens, thereby can tackle short delivery delivery date or immediate delivery phase.
Secondly, describe extracting the situation of handling substrate W midway.Figure 24 is used to understand extract and the mode time figure of the flow direction of the substrate W when checking the substrate W that handles midway.The setting productive temp time of each operation (I), (II), (III) all is T1, begins to finish operation (I) to the 4th plate base W4 from input and is extracted afterwards, through behind the review time T3, substrate W (n-m-4) is added subsequent processing (II).Like this, when substrate W (n-4) is added operation (II), the input productive temp time (T1+ α) at interval of the operation (I) of multi-disc (in the illustrated example being two) substrate W (n-m-3) after the conduct and W (n-m-2) is bigger than described setting productive temp time T 1 relatively, substrate W (n-m-1) afterwards and W (n-m) drop into the processing unit of operation (I) with original productive temp time T 1, then, in whole operations, to set productive temp time T 1 treatment substrate W swimmingly.Like this, when the making time (productive temp time) the operation (I) of the plurality of substrates of substrate W4 after operation (II) adds that the extraction that is through with is checked is longer than the setting productive temp time, afterwards, in whole operations, handle with the common productive temp time.
On the other hand, when extracting substrate W4 after the processing of operation (I) that be through with, because the processing unit of the operation after taking on (II), (III) does not drop into substrate, (productive temp time) is common twice so the substrate of operation (II), (III) is discharged at interval, and production efficiency reduces.Therefore, in the present invention, near main substrate case 101 processing unit that is being disposed at operation (II) (the first interim mounting table) or inspection are gone up with substrate box 102 (the second interim mounting table) and are finished operation (I), and under the situation of temporarily taking in the substrate that does not flow to manufacturing line, (when temporarily take in aftermentioned), when this substrate W (n-m+1) is dropped into the processing unit of operation (II), even check and extract substrate W4 from regular carrying road in order to extract, can make the productive temp time of back operation become setting productive temp time T 1 afterwards, thereby production efficiency can not reduce yet.
Secondly, the situation that specific processing unit is broken down describes.Figure 25 is the mode time figure of the flow direction of the substrate W when being used to understand specific processing unit and temporarily breaking down.In operation (II), under the situation that the processing unit of operation (II) after the processing of the substrate W3 that is through with breaks down, also can be after breaking down, several pieces (four) substrate W4～W7 are carried out the processing of operation (I) to set productive temp T1, next, several pieces (three) substrate W8～W10 are owing to the processing unit of operation (II) stops to handle adjustment, therefore to handle than setting the 1 long productive temp time (T1+ β) of productive temp time T.These plate bases W4～W10, even because after follow-up substrate (for example substrate W5 of relative substrate W4) finishes the processing of operation (I), can not be dropped in the operation (II), therefore, moved into and be received into successively in the main substrate case 101 between operation (I) and the operation (II).
After the processing that finishes operation (II) from the 3rd substrate W3 is through dwell time T4, when opening the processing unit of operation (II) once more, the before substrate of moving into of multi-piece substrate W4～W10 that is incorporated in the main substrate case 101 begins to be taken out of successively, and drops into the processing unit of operation (II) to set productive temp time T 1.And, comprise finally to drop into the later substrate of next substrate W12 of the substrate W11 of operation (I) than setting the 1 big productive temp time (T1+ β) of productive temp time T, dropped into operation (I) to set productive temp time T 1 successively, thereby all handled continuously swimmingly in the operation.
In the substrate transfer apparatus S of present embodiment, branch road carrying row L3 is corresponding with each processing unit A of cutting apart configuration in its both sides～D group both sides.Therefore, the travel distance of branch road carrier 103 can be shortened, the handling time of the substrate W that branch road carrier 103 carries out can be shortened.
In the substrate transfer apparatus S of the above embodiments, main substrate case 101 is located at the interim mounting table row of substrate L2 place with stationary state.Therefore, in the present embodiment, differently be provided with main substrate case 101 and check, the substrate W that extracts is accommodated in described inspection with mutually in 102, and utilize branch road carrier 103 should check to be transported to testing fixture Ma, Mb place with substrate box 102 integral body with substrate box 102.Its result, described inspection is moved into mouthful or is taken out of mouthful just one and get final product with the substrate W's of substrate box 102, so has its advantage of simple structure.
In the substrate transfer apparatus S of present embodiment, if the substrate W that will extract for inspection is accommodated in to check with in the substrate box 102, but it is accommodated in the main substrate case 101, then be difficult to this substrate W is joined to branch road carrier 103.But, under the situation that for example described substrate box 101 rotatably is provided with in horizontal plane, also can the substrate W that check be joined to branch road carrier 103 from described substrate box 101.Thus, do not need to check with substrate box 102 to have the advantage of simple structure of substrate transfer apparatus S.
In addition, though present embodiment be the substrate W that extracts be incorporated in check with the state in the substrate box 102 under, be that unit joins mode to branch road carrier 103 with each this detection with substrate box 102.But, also can be it not to be accommodated in to check, and join mode to branch road carrier 103 with substrate W monomer with in the substrate box 102.Thus, has the advantage that does not need to check with substrate box 102.
The substrate transfer apparatus S of present embodiment is a mode of utilizing substrate delivery/reception device Ea, Eb arbitrarily to carry out the handing-over of substrate W via main substrate case 101 (the first interim mounting table).But substrate delivery/reception device Ea, Eb also can be the modes of substrate W of directly joining.In this case, the needed time of handing-over of substrate is significantly shortened, thereby can further shorten TAT.
In the present embodiment, as the attached processing that the substrate W that handles is midway carried out, the situation about checking that extracts has been described.But,, also can be the processing of extracting beyond checking as attached processing.
For example, press the situation of design formation etc. at pattern Processing, the also oriented repair apparatus that is used for the bodging part carries out the example of branch road carrying etc.
In first and second each two the interim mounting table row of substrate L2 that organize of present embodiment, use as the keeping space that is used to store the substrate box of taking in processing substrate W midway in the part space in addition that main substrate case 101 can be installed.Thus, when specific processing unit A～D breaks down or manufacturing line integral body safeguarded, can temporarily unload and take in more substrate W from manufacturing line.That is the effect that, has " pooling feature of the manufacturing line " increase that makes the interim mounting table row of substrate L2.
The 5th embodiment.
Secondly, the 5th embodiment is described.In addition, in the present embodiment, to the inscape additional identical symbol common with the inscape of above-mentioned the 4th embodiment.
Figure 28 is the overall plan view of the semiconductor-fabricating device U1 of first embodiment, Figure 29 is the stereogram of pallet P, Figure 30 takes out of the plane graph that position Ra disposes the state of pallet P at the substrate of relative cleaning device A, Figure 31 is the amplification view of substrate delivery/reception device Ga, Figure 32 is the side plan view of annular conveyer K, and Figure 33 is the front cross-sectional view of annular conveyer K.
At first, the overall structure to semiconductor-fabricating device U1 describes.As shown in figure 28, this semiconductor-fabricating device U1, by see on the plane bight be slow toroidal annular conveyer K around constitute by each processing unit (cleaning device A, CVD device B, electro-optical device C, Etaching device D, testing fixture E) of the treatment process arranged in order of substrate W and the substrate storage storehouse F that is used for the substrate W of keeping before and after handling.And, between annular conveyer K and each processing unit A～E and substrate storage storehouse F, dispose substrate delivery/reception device Ga, the Gb of the handing-over that is used for carrying out substrate W between the two.In addition, on the position corresponding, annular conveyer K inboard, dispose the temporary transient storage appts L of substrate W with each processing unit A～E.Utilize above-mentioned annular conveyer K and each substrate delivery/reception device Ga, Gb to constitute base plate transfer device S.
In the substrate transfer apparatus S of present embodiment, substrate W utilizes annular conveyer K to carry with the state that each sheet ground is incorporated on the pallet P.This pallet P utilizes the effect of annular conveyer K to carry (advancing), and stops in the position corresponding with each processing unit A～E.And, utilize substrate delivery/reception device Ga, the Gb of corresponding configuration that substrate W is taken out of from pallet P, and move into each processing unit A～E with them.The substrate W of the processing among each processing unit A～E of being through with is taken out of from each processing unit A～E by substrate delivery/reception device Ga, Gb once more, and is moved into the pallet P (not taking in the pallet P of substrate W) of the sky of waiting on annular conveyer K, and side carrying downstream.Below, will take out of the position note work " substrate is taken out of position Ra " of substrate W from pallet P, will move into the position note of substrate W to the pallet P of sky and do " substrate is moved into position Rb ".Manage throughout among device A～E, by in turn carrying out above-mentioned operation, described substrate W is carried out predetermined process, and it is accommodated in the F of substrate storage storehouse.Among Figure 28, represent that by arrow the processing of substrate W flows to (portable cord).
At first, pallet P is described.As shown in figure 29, the pallet P of present embodiment is made of the composite material of resin or resin and metal.The tray main body 201 that constitutes this pallet P is for only taking in the cuboid frame shape of a plate base W, for described substrate W is moved into take out of and one side (with substrate delivery/reception device Ga, face that Gb is relative) formed to move into by opening and take out of opening 201a.Both sides at described tray main body 201 reach each face up and down, around will being located at predetermined distance by three reinforcement plates that stringer board 202 and transverse slat 203 constitute.Equally, the substantial middle portion at each face up and down of tray main body 201 and the back side is provided with other reinforcement plate of and described each reinforcement plate quadrature that constitute by stringer board 204 and transverse slat 205.And, being located on each stringer board 202 equal height position each other of two sides, each support wire 206 is installed with the state of giving tension force.The substrate W that is moved into pallet P is by each support wire 206 supporting.In addition, the arrow among Figure 29 represents that moving into of substrate W take out of direction Q.
K describes to annular conveyer.As shown in figure 30, the annular conveyer K of present embodiment is a dynamical type roller conveyer.That is, respectively install between the frame 207,208 rotation a plurality of board carrying rollers 209 that are arranged in parallel with predetermined distance are installed freely inside and outside.The interval of respectively installing frame 207,208 inside and outside described is wideer slightly than the length of the depth direction (length direction) of pallet P, and each pallet P takes out of opening 201a with the state configuration relative with the device frame 208 of the outside (outer circumferential side) with moving into of they.One end of each board carrying roller 209 is outstanding from the device frame 207 of inboard (interior all sides), and sprocket wheel 211 is installed respectively.Volume hangs with chain 212 on each sprocket wheel 211.Therefore, when driving rotating sprocket 211, make whole sprocket wheels 211 drive rotation by chain 212 when making drive motor M work.Its result, each board carrying roller 209 rotates to same direction, the pallet P of carrying (advancing) mounting on them.In the device frame 208 in the described outside, take out of position Ra with substrate and substrate is moved into the corresponding part of position Rb, to take out of substrate W and be provided with each notch 208a, 208b by otch respectively in order to move into.
Secondly, H describes to substrate lifting device.In addition, substrate lifting device H that the following describes and pallet arresting stop J and each processing unit A～E are provided with accordingly, and, their structure is all identical, therefore, substrate lifting device H and the pallet arresting stop J that only substrate that is disposed at relative cleaning device A is taken out of position Ra here describes.This substrate lifting device H, as Figure 31～shown in Figure 33, taking out of when being accommodated in pallet P upper substrate W or when the pallet P of sky moves into substrate W, move into the state that lifts this substrate W from support wire 206 and to take out of, its substrate that is disposed at annular conveyer K take out of position Ra and substrate move into position Rb under.And four substrate elevating arms 213 that can enter each board carrying roller 209 gap are each other liftably installed.At each supporting substrates W above the substrate elevating arm 213, and the backing roll 214 that is used for moving into channeling conduct when taking out of this substrate W is installed.The fulcrum shaft that each backing roll 214 is taken out of the horizontal direction setting of direction Q (with reference to Figure 31) quadrature with edge and moving into of substrate W is that the center rotates freely.
Be disposed at substrate when taking out of Ra place, position at the pallet P that will take in substrate W, each substrate elevating arm 213 rises.Then, give prominence to, and enter in the pallet P, lift the substrate W that is supported on each support wire 206 from the bottom surface sections of tray main body 201 from each board carrying roller 209 gap each other.Thus, the substrate W that is accommodated on the pallet P breaks away from each support wire 206, and can utilize substrate delivery/reception device Ga, Gb to take out of.In addition, be disposed at substrate when moving on the Rb of position at empty pallet P, each substrate elevating arm 213 rises.Therefore, the substrate W that is moved into by substrate delivery/reception device Ga, Gb is supported on each backing roll 214 of substrate lifting device H, can not occur producing the possibility of disturbing with each support wire 206 of pallet P.And when moving into described substrate W integral body in the pallet P, each substrate elevating arm 213 descends.Thus, substrate W is supported on each support wire 206.
Secondly, J describes to the pallet arresting stop.As shown in figure 33, in the positive downstream of described substrate lifting device H, be provided with the pallet P that is used to make by annular conveyer K carrying and stop at the pallet arresting stop J that substrate is taken out of position Ra.This pallet arresting stop J is by making liftably the keep plate of installing 215 outstanding from board carrying roller 209 gap each other, and the structure that the carriage P of carrying is stopped.This pallet arresting stop J is by being installed on proximity switch (not shown) work of the assigned position that respectively installs frame 207,208 inside and outside the annular conveyer K.Thus, the pallet P substrate that is disposed at annular conveyer K under the state of location is taken out of position Ra.
Secondly, substrate delivery/reception device Ga, Gb are described.As shown in figure 28, manage throughout and dispose substrate delivery/reception device Ga, Gb between device A～E and the annular conveyer K respectively.This substrate delivery/reception device Ga, Gb, to be joined to each processing unit A～E by the substrate W in the pallet P of annular conveyer K carrying, the substrate W after will being handled by each processing unit A～E utilizes described substrate delivery/reception device Ga, Gb to join and carries the processing unit A～E of operation backward to annular conveyer K.In the semiconductor-fabricating device U1 of present embodiment, corresponding each processing unit A～E is provided with any among two kinds of substrate delivery/reception device Ga, Gb.At this, using arbitrarily with respect to each processing unit A～E, substrate delivery/reception device Ga, Gb determine according to the structure of this processing unit A～E.Promptly, as cleaning device A and electro-optical device C and testing fixture E, under common environment during treatment substrate W, use is provided with the substrate delivery/reception device Ga of vacuum absorption device 216a at the leading section of drawing arm 216, as CVD device B and Etaching device D, under vacuum environment during treatment substrate W, take out of opening and close owing to need in handling these are moved into, so use is provided with the substrate delivery/reception device Gb of a pair of handing-over arm 217 (with reference to Figure 28).
As Figure 30～shown in Figure 32, each substrate delivery/reception device Ga, Gb are layed in pair of guide rails 218 guiding on the floor, can walk freely along the carrying direction of pallet P.In addition, these bases 219 are rotatable in horizontal plane.Be used to adsorb and move into and take out of drawing arm 216 and being used to guide a plurality of guide reels 221 of moving into the substrate W that takes out of of substrate W constituting to be provided with on the base 219 of described substrate delivery/reception device Ga.For example, make described arm 216 advance and retreat of drawing by make ball-screw 223 drive rotation by drive motor 222.
Like this, be incorporated in pallet P and the substrate W that is handled upside down takes out of position Ra at substrate and utilizes arbitrarily that substrate delivery/reception device Ga, Gb take out of, and move into each processing unit A～E.In addition, the substrate W that has implemented the processing that each processing unit A～E carries out is taken out of by substrate delivery/reception device Ga, Gb arbitrarily, and moves into the pallet P that moves into the sky of position Rb place waiting at the substrate of annular conveyer K.Then, be transported to the substrate corresponding and take out of position Ra with the processing unit A～E of back operation.Carry out above-mentioned operation among device A～E repeatedly by managing throughout, the substrate W that device A～E carries out predetermined process is managed in carrying throughout.
Secondly, the temporary transient storage appts L to substrate W describes.As Figure 28 and shown in Figure 30, in the inboard of annular conveyer K, with except the corresponding position of each processing unit A～D of testing fixture E on be provided with the temporary transient storage appts L of substrate W.This temporary transient storage appts L is for example for the substrate W that handles midway, because the fault of the processing unit A～E of operation or Maintenance and Repair thereafter and described substrate W can not be carried downstream side the time, the pallet P of this substrate W is taken in temporary transient keeping.This temporary transient storage appts L takes in the tray rack portion 224 of multi-disc pallet P and accepts the pallet P on the annular conveyer K and be used for that pallet P is moved into the pallet carry-in/carry-away device 225 of taking out of described tray rack portion 224 and constitute by being used for multistage.Described pallet carry-in/carry-away device 225 is rotation freely in horizontal plane, with annular conveyer K in the face of configuration, can move into take out of pallet P and with tray rack portion 224 in the face of configuration and can move into and take out of pallet P.Therefore, the part of device frame 207 of inboard of moving into position Rb at the substrate of annular conveyer K is in order to carry out that moving into of pallet P taken out of and cut, thereby forms notch 207a.Among Figure 30, represent that with dashdotted arrow processing from the pallet P that takes out of to tray rack portion 224 that move into flows to (portable cord).In addition, in the semiconductor-fabricating device U1 of present embodiment since the W of the frame portion former state of the inspection that testing fixture E carries out that is through be incorporated in the F of substrate storage storehouse, therefore, the temporary transient storage appts L (with reference to Figure 28) of relative testing fixture E needn't be set.
Secondly, the effect to substrate transfer apparatus S describes.At this, where to manage device A～E all roughly the same because the effect (the handing-over effect of the substrate W between the pallet P on the annular conveyer K and each processing unit A～E) of the substrate transfer apparatus S of each processing unit A～E is in office, so in the present embodiment, only the handing-over effect to the substrate W of cleaning device A describes.As shown in figure 28, in the past the device of the operation substrate W that utilizes board carrying car (not shown) etc. to move into substrate storage storehouse F only takes out of a slice by substrate delivery/reception device Ga, and it is received in the pallet P of the sky of waiting on annular conveyer K.Among Figure 28, represent to take in the pallet P of substrate W, represent empty pallet P with double dot dash line with solid line.Under this state, make drive motor M work and drive each board carrying roller 209 of rotation, pallet P is carried side downstream.Utilize proximity switch (not shown) to act on and make pallet arresting stop J work and keep plate 205 is risen, thereby make its upper end outstanding from each board carrying roller 209 gap each other.Thus, pallet P is positioned and stops at substrate corresponding with cleaning device A among the annular conveyer K and takes out of position Ra.
As Figure 31～shown in Figure 33, when pallet P stopped at the substrate plate and goes out position Ra, substrate lifting device H work was risen each lifting arm 214.Thus, the substrate W that is accommodated in pallet P is picked up and breaks away from each support wire 206.The arm 216 of drawing that constitutes substrate delivery/reception device Ga is advanced, with its leading section be disposed at substrate W leading section under.Make vacuum absorption device 216a work and will draw arm 216 and substrate W absorption, and former state it is retreated.The substrate W that draws from pallet P is supported on each guide reel 211 that constitutes substrate delivery/reception device Ga, and is configured in above the base 219.Then, make 219 rotations of described base, with its with cleaning device A move into opening 226 relative configurations.And the described arm 216 of drawing is advanced, substrate W is moved into cleaning device A via moving into opening 226.
As shown in figure 30, utilizing cleaning device A that described substrate W is carried out in the process of clean, substrate delivery/reception device Ga is guided by pair of guide rails 218 and moves, with cleaning device A take out of opening 227 relative configurations.In addition, the keep plate 215 of pallet arresting stop J is descended, and make drive motor M work that described pallet P is carried side downstream, and make it stop at substrate to move into position Rb.
Be through with cleaning device A processing substrate W via cleaning device A take out of opening 227 handing-over to substrate delivery/reception device Ga, and move at the substrate of annular conveyer K and move into the empty pallet P that position Rb waits for.The effect of substrate delivery/reception device Ga of this moment is an operation opposite when taking out of the substrate W that is accommodated in pallet P.Afterwards, in CVD device B, electro-optical device C, Etaching device D, testing fixture E, carry out same effect carrying substrate, thereby a plate base W is carried out predetermined process (monolithic processing) successively and it is accommodated in the F of substrate storage storehouse.
Secondly, the situation of the batch processing of carrying out with existing segmented mode is compared, and the processing time of the substrate W of above-mentioned substrate transfer apparatus S is described.Figure 34 is the mode time figure of the flow direction of the substrate W of expression will handle midway substrate W and utilize monolithic processing and batch processing normally to handle the time.In addition, therefore not corresponding because Figure 34 and Figure 36 are the time diagram that is used to understand the normal flow direction of substrate W with the treatment process of described embodiment, and reduced its operation quantity.Below, when expression one plate base W, additional label " 1 "～" n ".In addition, the processing time of each processing unit (productive temp time) is set at roughly the same.
In monolithic of the present invention is handled, each substrate (W1～Wn) with the processing unit of setting productive temp time T 1 and being dropped into operation (I) in and handle after, dropped in the processing unit of operation (II) and handled.In addition, the substrate W that takes out from the processing unit of operation (II) is dropped in the processing unit of operation (III) and is handled.Like this, (in other words, manage throughout under the situation about not breaking down in the device) under the situation of substrate W proper flow, (W1～Wn) flow to lower procedure successively in each operation, handles with the roughly the same setting productive temp time each substrate.
Specify above situation.Under situation of the present invention, as shown in figure 34, when the first plate base W1 is dropped into operation (I), utilize the processing unit of this operation (I) that substrate W1 is carried out predetermined process.When this processing finished, this substrate W1 was carried by annular conveyer K and the processing unit of quilt input operation (II).Follow this, the second plate base W2 is dropped in the processing unit of operation (I).Like this, in the present invention, substrate W1～W3 each sheet ground is separately dropped into each operation (I), (II) and is handled (monolithic processing) in (III).Relative therewith, in existing segmented mode, because multi-piece substrate W is focused in each operation, so the processing time of each operation is elongated.But under situation of the present invention, the TAT of each substrate W1～W3 (T2) compares extremely short with the TAT (T12) of the situation of segmented mode.In addition, the productive temp time T 1 of each substrate W1～W3 of the present invention is also short than the productive temp time T 11 of segmented mode.
In addition, graphical presentation shown in Figure 35 monolithic of the present invention is relatively handled and the relation of the processing sheet number of the substrate W of time of batch processing.In the figure, the situation that solid line 228 expressions monolithic of the present invention is handled, the situation of the existing segmented mode of double dot dash line 229 expressions.But this figure begins to as the total processing time of finishing the needed every plate base W of product taking-up from substrate W being dropped into manufacturing line, is assumed to be identical situation in monolithic processing and batch processing.In existing segmented mode, because for example 20 plate base W focus on, so, then can not obtain as the substrate W that finishes product if without its TAT (T12).But, in situation of the present invention, owing to be the mode that each sheet is handled, so if the TAT (T12) of process a slice amount then produces a plate base W.
Above-mentioned result, quantity as the substrate W (at product inventory) that is detained at goods (unfinished work) is reduced, thereby get final product with few circulating fund,, therefore have the managerial advantage of the good grade of turnover of capital owing to the recovery of finishing at short notice investment.In addition,, the keeping space of the substrate W in the manufacturing line is reduced, therefore have the low advantage of construction cost of clean room owing to minimizing at product inventory.Particularly in recent years, because the size of substrate W increases, the unit price of every plate base W is also high, so the minimizing that the shortening of above-mentioned TAT reaches at product inventory can produce big benefit.In addition, because the delivery cycle (delivery date) shortens, therefore can tackle short delivery delivery date or immediate delivery phase.
Secondly, the situation that the particular procedure device is broken down describes.Figure 36 is the mode time figure of the flow direction of the substrate W when being used to understand specific processing unit and temporarily breaking down.Be in operation (II), after the processing that finishes substrate W3, the situation that the processing unit of operation (II) breaks down, after breaking down, several pieces (4) substrate W4～W7 also can carry out the processing of operation (I) to set productive temp time T 1, afterwards several pieces (3) substrate W8～W10, owing to by the processing unit of operation (II) stop to handle adjustment, and to handle than setting the 1 long productive temp time (T1+ β) of productive temp time T.These multi-piece substrates W4～W10, even, therefore moved into successively and be accommodated in the temporary transient storage appts L between operation (I) and the operation (II) owing to after the processing of follow-up substrate (for example substrate W4 the is substrate W5 relatively) operation that is through with (I), can not drop into operation (II).
When after the processing that finishes operation (II) since the 3rd plate base W3 is through dwell time T4, opening the processing unit of operation (II) once more, multi-piece substrate W4～the W10 that is accommodated in the temporary transient storage appts L is taken out of successively by the substrate of moving into earlier, and drops into the processing unit of operation (II) to set productive temp time T 1.And, comprise finally to drop into the later substrate of next substrate W12 of the substrate W11 of operation (I) than setting the 1 big productive temp time (T1+ β) of productive temp time T, dropped into operation (I) to set productive temp time T 1 successively, thereby all handled continuously swimmingly in the operation.
